I have a 2001 foreman 450, with 29.5 terminators and with the 14% gear reduction it spins them decently. I’m fixing to put 30 mudder in laws and seeing that there a little heavier would like to know what would be my best option to spin them with no problem whether on the street or bumper deep in the thick stuff. A bigger gear reduction ( if so what size would be best) or boring the motor or both? Thanks
